BOILER-TUBE CLEANER.

SPECIFICATION forming part of Letters Patent No. 398,749, dated February26, 1889.

Application filed A t 1, 1888. Serial No. 281,653. (No model.)

To aZZ whom, it may concern.-

Be it known that we, HARVEY D. RIGE and Enws'r VoLKMANN, citizens of theUnited States, and residents, respectively, of the city of Brooklyn andthe city of New York, both in the State of New York, have inventedcertain new and useful Improvements in Boiler- Tube (.leaners, of whichthe following is a complete (.lescription, reference being had to To theaccompaning drawings, forming part of this specification.

Our invention relates to sectional watertube boilers, and its object isto n'ovide means for blowing off with stean'i-jels the soot and asheswhich aceunmlate on the outside of the tubes, the special objects of ourinvention being to provide means whercln; i he tubes may all be cleaned.sin'iultaneously without any cold air being admitted to thefire-chamber,

and also to so arrange the ljilowing device that although located in thefire-chamber it will not be burned out.

In the accompanying drawings, Figure 1 rep resents the steam jet. l ig.2 is a vertical lon- :2 5 gitiulinal section of the fire -chan'1ber online X X, slmwing the jet in position. Fig. 3 is a cross-section on lineY Y, showing in full lines the position of the jet when not in use andin dotted lines its position when 0 in use. Fig. 4C is a plan on line ZZ, showing in full lines the position of the jet when not in use and indotted lines its position when in use. liig. 5 aplan of thctopot' theboiler with the tube cleaner in position.

Similar letters of reference designate similar parts in the severaldrawings.

The tube-cleaner consists of a pipe, A, set at right angles to the tube1; of the boiler. On

this pipe, and at right angles thereto, is at- L 40 tached a row ofshort branch nipples. The

distance between centers of these nipples is the same as the distancebetween centers of the horizontal rows of boiler-tubes measured on aline perpendiular thereto and parallel with the pipe A. A pocket orrecess, P, is provided in the side wall, 'W, of the boiler, such recessbeing perpendicular to the boilertubes B. The upper part of the recessis provided with a fitting, O, of ,U-shaped-section,

. ted lines.

which is embedded in the masonry in such a way as to form a prolongationof the recess. The sides or wings of the fitting (l are provided withslanting slots S matching each other and pitching down toward the bottomof the recess l.

The pipe A is provided with a collar, I), having a side boss out of eachside of which projects a pin, E, which engages in the two slots S. Thecollar Dis secured permanently in position on the pipe A. The pipe Aruns through the ceilingot the fire-chamber, there being an opening cuttherefor in the brickwork. This opening is covered by a stationaryplate, G, which has an opening, g, covered by an additional plate, II,which latter is free to slide on the upper side ol the plate G insuitably-provided guides. The pipe A runs through the opening g andthrough a hole bored in the movable plate ll, in which it may freely beturned or raised and lowered. A hand-wheel, K. furnishes the means ofhandling the pipe A. A split collar, N, with a tightening-screw, (),isplaced on the pipe A above the plate H. L is ahose for supplying steamto the pipe A, the lower end of which 7 5 pipe is plugged at M. When notin use, the pipe A is in the position shown in full lines, Figs. 3 and4. The screw 0 on the split collar N being slack, the pipe A lies as lowas the slots S will allow it to fall and the pitch of those slots hasmoved the pipe into the recess P, where it is protected from directcontact with the flame. As afnrtherprecaution, the hand-wheel K shouldbe turned so as to bring the nipples to also inside of the recess I. Inthis position the plate H has moved as far to the left as possible. Whenthe pipe A lies in the above position, the sides of the pocket 1 limitthe range through which the jets issuing from the nipples a can play onthe length of the boiler-tubes B. Therefore to use the jets to bestan'lvantagc the tube A should be brought forward out of the recess 1.This is done by raising the hand-wheel K. The pin E, followingthe upwardand outward 5 pitch of the slots S, throws the pipe A out of the recessand into the position shown in dot- Then by letting the split collar Nslide down on the plate II and locking it there by means of the screw 0the pipe A may be held at any desired height, and still may be revolvedso that the jets of steam may be trained on an point in the length ofthe tubes.

\Vhile a combination of levers could be readily devised to give the pipeA the same throw out of the recess P as the combination of the slots Sand pin E, and while therefore we do not wish to limit ourselves to thismechanisnnas shown'and described,

hat we claim as our invention, and desire to secure by Letters Patent,is
